How it works

Réno’s AI orchestration layer connects a multilingual conversational interface with live operational systems — making flight, transportation, parking and weather data available in natural language, instantly and securely.

Actual architecture deployed at Luxembourg Airport — click to zoom.
  • 1. Conversational UI + TTS on lux-airport.lu
  • 2. RAG pipeline (retrieval-augmented generation) with vector KB
  • 3. Tools: live flights, luggage belts, parking, transit, weather
  • 4. Orchestration & guardrails (intent, tool routing, safety)
  • 5. EU hosting, GDPR, short retention

Designed RAG-first for accuracy and speed; tools and knowledge can evolve without changing the user experience.

Best use of AI

  • Multilingual understanding and translation, responses in natural language.
  • Real-time tools: flights, transportation, parking, weather, notifications.
  • Proactive UX (e.g., subscribe to flight updates).

Technical achievement

  • Cloud orchestration with vectorized knowledge base + fast embeddings.
  • Highly responsive web layer, fast even on mobile and tablets.
  • Graceful fallbacks, lightweight TTS integration, accessibility built-in.

Privacy by design

  • EU hosting, GDPR compliant, short retention windows.
  • Explicit consent flows for subscriptions and tracking.
  • No app needed — works directly on the airport website.

Impact (live to passengers, useful to operations)

Design is measured by outcomes. Réno reduces friction for travellers and pressure on the Info Desk.
